Doesn’t seem worth it for me.

Here’s Red’s offer.

And here’s the best offer via energymadeeasy.gov.au

My home made 6kW battery would struggle to compensate I think, but I need to do some more sums to be sure.

Another thing to watch is that on Red’s plan above, peak exists every day, whereas on my current plan, the entire weekend is off peak. That’s a big non-obvious difference.
